bUnit is a testing library for Blazor components that make tests look, feel, and runs like regular unit tests. bUnit makes it easy to render and control a component under test’s life-cycle, pass parameter and inject services into it, trigger event handl
It renders the layout and passes it the type of the component to add to theBodyRenderFragment. 组件 所有的组件都是普通的实现了IComponent接口的类。 IComponent接口的定义如下: public interface IComponent { void Attach(RenderHandle renderHandle); Task SetParametersAsync(ParameterView parameters); } ...
If catch-all parameters are used, every explicit parameter on DynamicComponent effectively is a reserved word that you can't pass to a dynamic child. Any new parameters passed to DynamicComponent are a breaking change, as they start shadowing child component parameters that happen to have the sa...
这里FromChild是ChildComponent中的属性,属性使用Action<string>数据类型将值从Child传递给Parent Component。在Parent中,有相应的接收器函数ReceivedFromChild和字符串参数,这将在ChildComponent中按钮单击并触发通知时触发PassToParent,但是为了通知状态已在父组件中更改,我们使用StateHasChanged()的内置Blazor函数通知组件其状...

//Define event[Parameter]publicEventCallback<int> CurrentCountChanged {get;set; }//Call eventawaitCurrentCountChanged.InvokeAsync(CurrentCount);//bind event<component @bind-CurrentCount:event="事件名称"></component> if you require multiple listeners, you can useAction<T>. Otherwise, it would be...
Use a CascadingParameter to pass the parent TabControl component into its child TabPage components. 下面看最终效果图: 实操开始: 请先创建一个Blazor项目(Blazor Client或者Server皆可,我们以Blazor Server为例), 第一步,创建两个组件:TabControl和TabPage。TabPage组件有一个父TabControl属性引用(属性名Parent,...
Razor components work in a similar fashion, although the component properties must also be marked with the [Parameter] attribute to be considered component parameters.The following Counter component defines a component parameter called IncrementAmount that can be used to specify the amount that the ...
